Privacy-Preserving Blockchain Framework for Autonomous Vehicles

OmniGuard V2X – Privacy-Preserving Blockchain Framework for Autonomous Vehicle Networks

As autonomous vehicles and smart city infrastructures continue to evolve, secure communication between vehicles and surrounding systems has become a critical challenge. Vehicle-to-Everything (V2X) networks enable real-time data exchange between vehicles, infrastructure, and other entities, but they also introduce significant risks related to data integrity, privacy, and cyberattacks. OmniGuard V2X was developed to address these challenges by building a decentralized, privacy-preserving security framework tailored for next-generation autonomous systems.

At its core, OmniGuard V2X integrates blockchain technology to create a tamper-proof communication layer. Instead of relying on centralized authorities, the system uses a distributed ledger to validate and store inter-vehicle communication data. Each message is cryptographically linked using SHA3-256 chaining, ensuring that any attempt to alter data is immediately detectable. This approach significantly enhances trust and transparency within the network.

Privacy is a central focus of the framework. Traditional authentication systems often expose sensitive information such as vehicle identity or location. To solve this, OmniGuard V2X implements Zero-Knowledge Proofs (ZKP) and Pedersen Commitments, allowing vehicles to verify their authenticity without revealing private data. This ensures that communication remains both secure and anonymous, which is essential in real-world deployments where privacy concerns are paramount.

To prepare for future cybersecurity challenges, the system also incorporates post-quantum cryptographic techniques. As quantum computing continues to advance, many existing encryption methods risk becoming obsolete. OmniGuard V2X addresses this by integrating cryptographic layers designed to remain secure even in the presence of quantum-capable adversaries, making the system forward-compatible with emerging threats.

Another critical aspect of the system is its resilience. In distributed networks, nodes may fail or behave maliciously. To handle this, the framework is optimized with Byzantine Fault Tolerance (BFT), ensuring that the system continues to operate reliably even when some nodes are compromised. This level of robustness is essential for maintaining safety in autonomous vehicle environments.

The implementation leverages a combination of edge computing and embedded systems, including devices like NVIDIA Jetson Nano, Raspberry Pi, and ESP32, enabling localized processing and real-time decision-making. Integration with perception systems using YOLOv8 further enhances situational awareness, allowing the framework to operate effectively in dynamic environments.

Overall, OmniGuard V2X represents a comprehensive approach to securing autonomous vehicle networks. By combining blockchain, advanced cryptography, and edge computing, it delivers a scalable, future-ready solution that prioritizes both security and privacy in intelligent transportation systems.
